Background ========== The Apache HTTP server is a very widely used web server. mod_jk provides the JK module for connecting Tomcat and Apache using the ajp13 protocol. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apache/mod_jk < 1.2.21-r1 >= 1.2.21-r1 Description =========== ZDI reported an unsafe memory copy in mod_jk that was discovered by an anonymous researcher in the map_uri_to_worker function of native/common/jk_uri_worker_map.c . Impact ====== A remote attacker can send a long URL request to an Apache server using Tomcat. That can trigger the vulnerability and lead to a stack-based buffer overflow, which could result in the execution of arbitrary code with the permissions of the Apache user. Workaround ========== There is no known workaround at this time. Resolution ========== All Apache Tomcat users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_jk-1.2.21-r1" References ========== [ 1 ] CVE-2007-0774 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0774 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-16.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
